Development The film was based on a story by Michael Syson, who worked for the BBC. Director Anthony Harvey said Syson "wrote it as kind of a short story, a series of ideas with a very strong story line but not really a script." Harvey said "The moment I read ''Eagle's Wing'' I knew very clearly the kind of things I wanted visually, and talked to Billy Williams for days about it." Financed was raised from the Rank Organisation, who made it as part of a slate of eight films with an estimated total budget of £10 million. (The others were
Wombling Free,
The 39 Steps,
The Lady Vanishes,
The Riddle of the Sands,
Silver Dream Racer,
Tarka the Otter and
Bad Timing.)
Shooting The film was shot in nine weeks in and around
Durango, Mexico in early 1978, finishing by April. Harvey says this was "short but we had the luxury of a small unit." He looked for unusual landscapes that appeared "like the surface of the moon". "Mexico is a most thrilling country to work in," said Harvey, who in August 1978 was planning on making another film there, a version of the novel
Under the Volcano.
Post Production Harvey says after filming was complete and he was on another project,
Players, "the money people came in and... made a number of cuts and put back some things I had cut out." ==Release==
